Re: PDF structures

To expand on what Bevi said (because I do have my copy handy *smile*):

According to 32000-1, lists are considered Block Level Structure Elements
(BLSE) in PDF, so nesting one inside the other would be a bit weird. A
Paragraph is considered a "low-level division of text". If you nest a list
inside a Paragraph, it will probably be flagged as incorrect usage in
something like CommonLook Validator (if you're doing QA with that tool),
but not sure how PAC 2.0 would look at it. For nested lists, you should
place them inside the <LBody> tag, which can also contain the <P> tag, or
other BLSE (per Table 336 in 32000-1).

Hope this helps,
